Andrew has already played 32 minutes on his video game today and wants to play an additional 15 minutes each of x games after school today. What equation can be used to find y, the total minutes Andrew will play video games today?
Answers
Answer:
y = 15x+32
Step-by-step explanation:
Given
y to be the total minutes Andrew will play video games today
x is the total number of games played after school
If he wants to play an additional 15 minutes each of x games after school today, the total minutes he will use for the x games will be 15* x = (15x)minutes
We are told that he has initially spent 32minutes on video games. hence;
Total minutes Andrew used on games y = (15*x)+32
The required equation will be y = 15x+32

C.27x^9+y^6
D.81x^24+8y^40
Answers
Answer
C. 27x⁹+y⁶
Explanation
We have to test all the expressions
A.-24a^15+125b^18 = -24a¹⁵+5³b¹⁸
= -24(a⁵)³ + (5b⁶)³
-24a^15+125b^18 ⇒ Is an expression of sum of cubes.
B.-64a^27+b^8 = -4³a²⁷+b⁸
= (4a⁹)³ + b⁸
Not a sum of cubes since 8 is not divisible by 3.
C. 27x^9+y^6 = 3³x⁹+y⁶
= (3x³)³ + (y²)³
27x^9+y^6 ⇒ Is an expression of sum of cubes.
D. 81x^24+8y^40 = 81x²⁴+8y⁴⁰
= 81(x⁸)³ + 2³y⁴⁰
81x^24+8y^40 ⇒ Is an not expression of sum of cubes.
